- He admitted to calling Evra that phrase (on numerous occasions during the game)
- His argument was that it was normal from where he comes from
- Research was done
- Research showed that is not true
- Guilty

Not hard to comprehend.

It's actually far from being that simple, and I'm not entirely convinced he would have been guilty in a court. The FA even stressed that they found him guilty on the balance of probability, not proven beyond reasonably doubt, which is what it would have to take for him to be found guilty in a court. Also the words nergo and negrito are not inherently offensive in Uruguay like they are in England, but they can be used offensively, eg. Suarez could call some of his black teammates on the Uruguayan national team 'negrito' and it would be normal and acceptable.
